ROLLER SKATE.

application'filed March 15, 1923. Serial No. 625,239.

- To all whom it may concern:

7 3e it known that I, PERCY O. GinsoN, a citizen of the United States ofAmerica, residing at Kokomo, in the county of Howard and State ofIndiana, have invented certain new and useful Improvements in RollerSkates, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to roller skates of the four wheel class and hasspecial refer' ence to a'skate having metalllc parts stamped and pressedfrom sheet metal to form a strong and durable skate structure The objectof my invention is to provide a skate which may be adjusted to fit shoesof various sizes and such adjustment is accomplished by an extensionmember slidably mounted relative to bearing members attached to the soleand heel piece of the skate. The configuration of the bearing andextension members is such as to afford a rigid longitudinal girderlengthwise of the skate insuring a substantial platform for a '25 shoe,besides preventing twisting or lateral displacement of one bearing-member relative to the other. With the skate firmly secured to ashoethere is no lost motion between the parts of the skate which would36 cause a loss of control when skating, and these advantages are gainedby metallic parts that can be easily and quickly assembled to provide astructure free from injury by ordinary use and highlyeificicnt as arolling foot piece.

The construction enterin into the skatehe sole piece and adjacent thetoe of this sole piece are opposed transversely alining shoe solegripping members or clips 2 slidably held on the lower face of the solepiece by rivets 3 extending through slots 40f the members or clips 2.The confronting depending ends of the clips or members 2 are articulatedby a right and'left hand screwthreaded connecting member 5- which may berotated to adjust the cli or members to and from each other, and it isby, virtue of these clips or members that the sole piece 1 may beattached to shoe soles of various widths.

The reference numeral 6 denotes a heel piece having an upstanding lug?and riveted or otherwise connected to said lug and also to the sideedges of the heel piece 6 is a strap member 8 adapted to embrace therear portion of the shoe and permit of straps or other flexible membersbeing employed for attaching the heel piece to the shoe, whereby thestraps may cooperate with the clips or members 2 in retaining the skateon a shoe.

Connectedto the lower faces of the sole and heel pieces 1 and 6respectively are longitudinally alining channel bearing members 9 and10, said members being connected to the sole and heel pieces by rivets11 or other fastening means. The bearing members 9 and 10 are stamped orpressed from sheet metal and said. members have depending parallelflanges 12 and apertured bearing lugs 13. Suitably mounted in thebearing lugs 13 are transverse axles 14 provided with lug spacingsleeves 15 and rollers or wheels 16. As shown the rollers or wheels 16are on the ends of the axles 14, thus providing a four Wheel skate. Therollers or wheels 16 may be of an anti-frictional type made of metal orany other type of roller or wheel may be used.

The reference numeral 17 denotes a channel shaped extension memberslidable in the bearing members 9 and 10,,said extension member havingparallel flanges 18 against the inner faces of the bearing flanges 12.The ends of the extension member 17 are provided with longitudinal slots19, and mounted in each of the bearing members is a bolt 20 providedwith a nut 21 and suitable washers 22. The bolts 20 may have the headsthereofin openings 23in the sole and heel pieces 1 and 6 and with thewashers 22 engaging the extension member 17, the bolts as I .20 may betightened and the extension member clamped against the bearing members 9and 10 to hold the sole and heel ieces in anadjusted position relativeto eac other.

It will be noted that the slots 19 will provide clearance for some ofthe heads of the rivets 11 and that the channel extension no member willcooperate with the channel bearings in forming a rigid longitudinalgirder lengthwise of the skate, it being practically impossible to breakdown such girder by the Weight of a person on a pair of skates.

One embodiment of my invention has been illustrated but it is to beunderstood that the structural elements are susceptible to suchvariations and modifications as fall within the scope of the appendedclaims.

What I claim is:

l. A roller skate comprising sole and heel pieces having means forattachment to a shoe, bearing members rigidly connected to said sole andheel pieces, roller equipped axles carried by said bearing members, anextension member slidable between said bearing members, and means fixedrelative to said sole and heel pieces adapted for fixing said extensionmember relative to said sole and heel pieces.

2. A roller skate as called for in claim 1, wherein said bearing andextension members have a cross sectional shape lending a rigid girderlikestructure lengthwise of the skate and in Width approximating thedistance between the rollers of each axle.

3. A. roller skate comprising sole and heel pieces, adapted forattachment to a shoe, channel bearing members connected to said sole andheel pieces and provided with sets of: bearing lugs, a channel extensionmember corresponding in cross section to said channel bearing membersand slidable in said channel bearing members and between the bearinglugs thereof, said channel extension member being longitudinallyslotted, nut equipped bolts fixed relative to said sole and heel piecesand extend ing through the slots of said channel exten sion member tofix said extension member relative to said bearing members, and rollerssupported from the bearing lugs of said bearing members.

In testimonywhereof I afiix my signature in presence of a Witness.
